Title: Add functionality to import themes to incognito tab Description: It would be very useful if Brave could offer the option to import themes to the incognito tab in a more accessible way. Currently, users have to manually modify configuration files to customize their themes in the incognito window. Implementing an option to import themes from the Chrome Web Store or from local files without the need to edit configuration files directly would enhance the user experience, allowing for greater customization in this mode. Priority: High
It’s still incognito mode, so it’s a weird idea.
But it’s pretty interesting, and I’d also like to make incognito mode creepy, like a secret vault, so I vote 
for this feature!
